Rita Ora and Cara Delevingne clearly didn't get the '80s themed memo for Fran Cutler’s birthday party last night in London.

Rather than going all out a la Kate Moss, Rita rolled up to The Box wearing a little white Missoni dress under a clear Terra New York trench coat, those white Chanel boots she gushed over on Instagram and her new favorite Chanel lego clutch.

Cara went in the complete opposite direction, showing off her money-making abs in a Tokyo crop top, powder blue blazer and matching pants, fresh Jordan sneakers, a 100 Percent Zero beanie and Ray-Bans.

Too bad the party wasn't '90s themed; they could have been the modern day Cher and Dionne!
